SPRING-WHEEL.

Specification of Letters Patent.

Patented April 27, 1909.

Application filed May'25, 1908. Serial No. 484,848.

; To all whom it may concern: 7 I 1 Be it known that 1, WILLIAM J.STORES, a citizen of the United States, residing at Ohicago, in thecounty of Cook and State of Illinois, have invented certain new anduseful Im rovements in Spring-Wheels; and I do dec are the followin tobe a full, clear, and exact description oi the invention, such as Willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to spring wheels, and

the object of the invention is to improve upon the present type of wheelnow in common usep Heretofore thesprings of the wheels have beendisposedinsi e and outside ofthe felly and theoutside springs were protected byan annular sheath. It was impossible to adjust thetension of thisoutside s ring without his rendered the adjustment expensive and tediousand it is'the cliflfiject of my invention tdbbviate culties in a cheapand eflicient manner. 9

Broadly stated, the invention comprises "means to ad'ust the outerspring which is covered by the sheath, and means whereby 2 ;-saidadjusting means may be operated withoutremoving the sheath.

Inthe drawings,Figure 1 is a fragmengta side elevation with parts brokenaway; ,m Fig. 2 is a transverse vertical section thro h one of theadjusting devices.

'Re l erring more es ecially tothe drawings 1 represents the fe y and 2the tire upon wine is mounted the usual auxiliary cushion 3. In thisinstance the cushion is held in place by flanges 4 which extend'around'the tire and downwardly from the tire 2.

es 4 extend beyond;the tire 2 so as to overlap the sides of the rubbercushion 3. The felly is .apertured at 5 to receive the spring receivingbolt 6 which is threaded at both ends as at-7'and 8 to receive theadjust- 1 ing nuts 9 and. 10, which hold the compression springs 11andfl12-betwen the nuts and the felly. The upper end of the adjustingbolt 6 is loosely engaged upon the under side of the tire 2 and the umerend projects beyond the felg.

xtendin up from the felly 1 on either side thereo are annular flanges 13which overlap the flanges 4 and thereby form a The compartment 14 inwhich the outer springs 11 are located.

The nut 9 is made square-and is of suflicient diameter to have its sideengage the inner part of the flanges 4, so as to prevent turning thereofand the inner end of the bolt or rod 6 is squared as at 15 so as toreceive a Wrench or other suitable tool whereby the rod may be turnedwithin the nut 9 so as to adjust the same within the nut and therebyadjust the tension of the springs 11 and 12. The nut 10 may be adjustedat any time as it is freely ex osed as shown.

y providing a device of this character the resiliency of the wheel maybe adjusted at a moments notice without any appreciable trouble or timeconsumed. From the fore oing description, taken in connection with t eaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Varlou's changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention as defined in theappended claims. I

\ Havin thus described and ascertained the nature oi my invention, whatI claim as new and desire to secure by Letters-Patent, is:

1. In a sprin wheel, the combination with an apertured f5 from, inwardlyextending wa ls carried by the tire for forming a chamber between thetire and the felly, rods slidably mounted in the apertures of the fellyand adapted to loosely engage the tire, springs mounted upon the rodsWithin the chamber, nuts carried upon said rods Within the chamber andadapted to engage the walls to hold the same from turning, and a squaredwrench receiving end on the rod for turning the same within the nut soas to adjust the nut without entering the chamber, together with meansto hold the tire and felly in alinement.

2. In a spring wheel, the combination with an apertured felly, of a tireseparated therefrom, inwardly extending walls carried by the tire forforming a chamber between the tire and the felly, rods slidably mountedin the apertures of the felly and adapted to loosely engage the tire,springs mounted upon so i ly, of a tire se arated therethe rods withinthe ohamber, nufisparried upon said rods within the chamber and adaptedto engsige thewwallsto hold the same from turning, nuts on theyrodsWithout the dhamber, spr" s arringed' between the last named nuts anthefelly, and flanges carried by the folly extending'beyond the walls tohold the tire and felly 1n alinement.

I In testimony whereof, I'have hereunto set my hand. in-prosenc'e of twosub scribing 10'
